Emergency shut down
The movement of the underfeed combustion system can be stopped at any time by acti-
vating the emergency cut-off switch. In addition, opening the combustion chamber door,
the boiler door, or removal of the ash container will stop movement in the system. No
more fuel will be conveyed to the system.
The emergency cut-off does not immediately stop the combustion process in the
combustion system. The fire will continue to burn for a long time. Allow the fire to burn
down (see also «5.1 General instructions»).
